Insert bearings in the NSK UEL2 line combine a ball bearing with a longer inner ring and locking by set screws. They fit into split or solid housings, depending on the series, and suit shafts that turn while the housing stays fixed to the machine frame. When a unit has to be installed or swapped out without major dismantling, this style of bearing is often the practical answer.

Reading the code helps you order the right variant. The letters UEL mark an insert bearing with an extended inner ring and set screw locking; the first digit 2 gives the diameter series; the remaining digits define the shaft size. Take UEL204-012D1W3: the -012 suffix points to a 3/4 inch shaft. UEL204D1W3 is the metric counterpart at 20 mm. The D1 suffix denotes an execution with special sealing, while W3 covers an additional design feature, depending on the code. Further examples in inch sizes are UEL205-013D1W3, UEL205-014D1W3 and UEL205-015D1W3, with UEL205-100D1W3 as the 25 mm metric version, depending on the code.

Typical duty covers conveyors, belts, elevators, mixers, food processing machines, packaging equipment, fans, pumps and transmission systems in manufacturing plants. Because the housing can stay bolted to the structure and only the insert is changed, maintenance work is simpler and downtime shorter. Production lines that need a sturdy, easily replaceable bearing unit are the usual home for this series.

Selection comes down to shaft diameter in metric or inch, housing type and operating conditions. Sealing in the UEL2 series guards against dust and moisture, and set screw locking permits fast mounting on shafts with suitable tolerance, depending on the series. Check that the housing is aligned and lubricate as the manufacturer recommends. Where the shaft shows wear, a wear sleeve or a new shaft may be the better route.

Interchange is possible with other brands that use the same dimensional nomenclature, depending on the series. If you only have another maker's code or a part you cannot identify, send the details and we will point you to the compatible alternative. MR supplies the NSK brand and can quote the exact code you need.
